FLUID-ACTUATED TURBINE.

Application filed October a; mo. Serial so. 585,240;

To all whom it may concern:

Be it known that I, WILLIAM J. A. LON- DON, a subject ofthe King ofEngland, and a resident of Hartford, in the county of Hartford and Stateof Connecticut, have in-' vented new and useful Improvements inFluid-Actuated Turbines, of which the following is a specification. I

This invention relates generally to fluid actuated turbines, andparticularly to. the

construction of the rotor or bucket wheel, and has for its object theimprovement in the construction of the rotor or bucket wheel of fluidactuated turbines of the type where- 1 in the buckets are arranged intheperipheijy of the rotor.

The invention is illustrated in the drawings in which Figure 1 is a sideview of part of abucket with one side plate removed showing some of thebuckets in central section and others in side elevation. Fig. 2 is asectional view on the line 2, 2, of Fig. 1. Fig. 8 is a top view of oneof the buckets;

Rotors made'in accordance with my invention comprise two side plates a,b, circumferentially grooved on their opposing surfaces near their outeredges as indicated forms the top of the other bucket, producinga chamberiiiclosed on all but one side and having a curved rear wall. The sideribs 4, 4, .on the buckets fit into thecircumferential grooves o in theplates. and pins 12 pass through the holes'cZ in the plates and throughan apertured boss 13 on the buckets, these pins being headed over attheir outer ends to tie the plates together. There is thus provided arotor or bucket wall in which the parts are firmly pressed andinterlocked providing a structure which 'will withstand high speedwithout-serious deflection. f

1. A bucket member adapted" the rotor of a fluid actuated turbinecomprismg in an integral structure a bottom plate, 5.

and upstanding flange forming side and rear walls, the latter beingcurved, anda. depend? ing stiffening web transversely"o said botff tomplate. E

2. A rotor comprising a pair and bucket members arranged instep fortitside plates;

mation' between the edges 'ofsaidjplatesp each bucket member comprising.a chamber open: at top and front and havinga -curved' rear wall, thebottom of one'cliambe'r' form;

ing the top of an adjacent ehamb er,,means for securing 831d bucketniembers' n. pl e-,;

and a stifiening webon the bottom of 3( In a rotor the combination witha pair of side plates, of bucket members arranged'in; step. formationbetween the. "edges of. .said

plates, and means for securing them in place," each bucket member beingformed.inari iri-v tegral structure, with bottom plate,- sideandicurvedrear walls and a depending st'ifi'ening web.-

4. In a rotor the combination withiside plates, of'bucket membersofiiitegral structure open on to andfront and having a curved. rear waland a stifi'ening web depending from the bottom, said bucketsbeingadapted for arrangement one above the other in step formation betweensaid side'plates, pins extending between said-plates and a boss on theunder side of the buckets apertured to receive said pins. v

In a rotor the combination with a pair of side plates having circulargrooves in their opposing surfaces, buckets having side 1 ribs fittingin said grooves, and a stiffening web depending fromtheirunder side, and

pins extending from plate to plate through a boss on said buckets toticsaid plates to- I l getlier and hold said buckets in place.
